Mike Maxwell was a ranger at a wildlife preserve in the shadow of Mount Kilamanjaro in Africa. Because of his great strength and fighting skill, he agreed to a wrestling match against the local village champion, a brown gorilla named Djubai. He was humiliated when the ape defeated him in a matter of seconds. He tried to wash himself off in a local watering hole, only to be attacked by a lion. Mike was shocked to discover his powers when he merged the jungle cat with a nearby warthog. He discovered the lake had been contaminated by toxic waste, and splashing the water on himself had mutated his body. With his new skills in tow, Mike defeated Djubai in a rematch and claimed the ape's mask and title for his own. Ever since, Mike has used his admittedly unconventional powers to fight crime wherever he finds it, as well as protecting his home and animal friends in Africa.
